Antimicrobial Compounds that Inhibit FTSZ Protein (U.S. Patent Number 61/446,978)

Acronym: Not Available NIDDK Contact: Principal Investigator(s): Carole Bewley


This invention, offered for licensing and commercial development, relates to a new class of naturally occurring antimicrobial compounds called Chrysophaetins, and to their synthetic analogues. Isolated from an alga species, the mechanism of action of these compounds is through the inhibition of bacterial cytoskeletal protein FtsZ, an enzyme necessary for the replication of bacteria. FtsZ is responsible for Z-ring assembly in bacteria, which leads to bacterial cell division. Highly conserved among all bacteria, FtsZ is a very attractive antimicrobial target.

The chrysophaetin exhibits antimicrobial activity against drug resistant bacteria, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecalis (VRE), as well as other drug susceptible strains.
